Sequencer: Scene Strip Performance

     - Merged SEQ_OFSDRAW with V3D_OFSDRAW and define in the
       DNA_view3d_types: Due to this FSAA always kicked in making the
       rendering slow.
     - Removed `Texture Solid` and `DOF`.
     - Now when chosing Solid rendering the settings
       of the original scene is used.
     - Added a global override to use scene specific shading. In the
       Future we will need to enhanced this so user can change the
       settings.
     - Added support for LookDev. LookDev crashed as it needed the
       `evil_C` what was not set
     - LookDev mode will always show the scene + world lights.
